NXP Powers Efficient Lighting Introducing Dimmable SSL2103 LED Controller IC

NXP Semiconductors, a leading supplier of chipsets for energy-efficient IC based lighting solutions, today announced the introduction of a new LED controller, the SSL2103, extending NXP’s successful product family of AC/DC LED drivers(SSL2101/SSL2102) for a wide range of lighting applications such as retrofit lamps, the SSL2103 includes the functionality and performance of its sister product, the SSL2101, while extending the application reach towards higher power solutions.

The SSL2103 is a versatile device for all AC/DC LED lighting segments with extended power range and extended dimmer compatibility, making it suitable for both dimmable and non-dimmable LED lamps. Furthermore, each product of the SSL210x family seamlessly integrates the same controller functions for easy proliferation into a wide range of LED lamp applications.

• Flexibility for any power
• Natural dimming curve via logarithmic correction, optimized for human eye response down to 1%.
• Start-up from rectified mains voltage (100, 110, or 230 V)
• Supports majority of available dimmers (TRIAC, transistor)
• External bleeder transistors for dimmer interoperability
  - High integration reduces component count
  - Ideal for small form-factor applications
  - Buck, flyback, isolated, and non-isolated configurations
  - Thermal-enhanced and small SO14 package
• Meets safety and power-factor regulations
  - Built-in, dedicated circuitry for optimized valley switching
• Built-in demagnetization detection
• Built-in protection circuitry

• SSL retro-fit lamps
• LED modules (LED spots, down lights, lamps, etc.)
• LED strings, especially in retail displays

The SSL2103 is designed to target higher power LED lighting (PAR20, PAR30 and PAR38) and to bring the complete flexibility to lamp designers in terms of power rating, form factor and dimmer control.

“As the global lighting industry embraces ‘digital lighting,’ more electronics are being built into each bulb creating smart, efficient and long-lasting alternatives to incandescent lighting. LEDs represent the future,” said Jacques Le Berre, marketing director, Lighting, NXP Semiconductors. “We are proud of the success of the SSL2101 because it highlights how our product is meeting market demand for LEDs and setting the pace for the industry to deliver more energy-efficient lighting solutions.”

The SSL2103 includes the functionality and performance of the SSL2101 and SSL2102 while extending its application reach towards a higher power domain. This reach is achieved through external power switches and its ability to operate dimmable or non-dimmable ballasts. Similar in design to the previous versions, the SSL2103 can achieve a lifetime performance of more than 75,000 hours at nominal operating temperature. NXP products in the AC/DC LED portfolio offer immense versatility for application materials and can be applied to isolated or non-isolated lamps. In addition, they can also be applied in 100V, 110V or 230V AC network and form factors for E27, GU10 or PARx lamps. The portfolio of products also includes integrated switches and bleeder circuitry, enabling a small form factor and less PCB surface.

NXP will be exhibiting at Lightfair International, taking place May 12-14, 2010 at the Las Vegas Convention Center. The company will be demonstrating its broad portfolio of high voltage solutions, emphasizing superior control of deep dimming and highly efficient current control for CFL and SSL technologies at booth #2635.
